Description
Technical field
The utility model belongs to steel-making oxygen blowing apparatus technical field, is related to a kind of steel-making steep-taper quick change oxygen rifle.
Background technology
Oxygen rifle is the visual plant of modern converter oxygen furnace steel, its main function be into converter provide smelt required for
Oxygen, oxygen projects by oxygen gun sprayer, the oxygen jet of formation, through high-temperature furnace gas impact in weld pool surface, penetrates molten
Pond chemically reacts with molten steel, meets to smelt decarburization, heats up and remove deimpurity needs.At present, in the prior art due to
The design of gun body appearance structure geometry is unreasonable, exists：When changing rifle can not the efficient and convenient, body of a gun dry slag the problems such as, oxygen rifle
Performance directly affect the operating efficiency of pneumatic steelmaking.
The content of the invention
The utility model overcomes above-mentioned defect, it is therefore an objective to by the way that the oxygen rifle body of a gun is designed into steep-taper, works as rifle
Body be stained with after slag the slag that because " expanding with heat and contract with cold " and slag are in the presence of self gravitation, is bonded on the body of a gun can Automatic-falling, solve
The problem of steel making oxygen lance body of a gun dry slag, there is provided steep-taper quick change oxygen rifle is used in one kind steel-making.
Steep-taper quick change oxygen rifle content Description is used in the utility model steel-making：
Steep-taper quick change oxygen rifle is used in the utility model steel-making, it is characterised in that：It is by oxygen gun sprayer, wide-angle Taper Pipe, straight
Section, inverted cone segment, oxygen rifle outer tube, guide plate, the sealing shroud of gun body and " O " type sealing ring are formed, wide-angle Taper Pipe successively with straight section
It is welded and fixed to connect as one to form the body of a gun with inverted cone segment, oxygen rifle outer tube, oxygen gun sprayer is arranged on the front end of wide-angle Taper Pipe, greatly
The taper of angle Taper Pipe is more than 1o, is provided with guide plate at the rear portion of oxygen rifle outer tube, the sealing shroud of gun body by " O " type sealing ring and
Lift cart is tightly connected.
The utility model steel-making use steep-taper quick change oxygen rifle, have oxygen blowing it is steady, it is cost-effective, rational in infrastructure, province
The characteristics of Shi Shengli.Oxygen rifle dry slag fast-falling can be made, change rifle process rapid and convenient, parameter stability is made steel, so as to improve oxygen
The service life of rifle, the overall technology performance of oxygen rifle are greatly enhanced.
Brief description of the drawings
Fig. 1 is steel-making steep-taper quick change oxygen rifle structural representation；
In figure：1 be oxygen gun sprayer, 2 be wide-angle Taper Pipe, 3 be straight section, 4 be inverted cone segment, 5 be oxygen rifle outer tube, 6 be oriented to
Plate, 7 be the sealing shroud of gun body, 8 be " O " type sealing ring.
Embodiment
The utility model steel-making is achieved in that with steep-taper quick change oxygen rifle and illustrated below in conjunction with the accompanying drawings.
See Fig. 1, steep-taper quick change oxygen rifle is used in steel-making, be by：Oxygen gun sprayer 1, wide-angle Taper Pipe 2, straight section 3, inverted cone segment 4,
Oxygen rifle outer tube 5, guide plate 6, the sealing shroud 7 of gun body and " O " type sealing ring 8 are formed, wide-angle Taper Pipe 2 successively with straight section 3 and fall
Cone section 4 is welded and fixed with oxygen rifle outer tube 5 and connects as one to form the body of a gun, and oxygen gun sprayer 1 is arranged on the front end of wide-angle Taper Pipe 2,
The taper of wide-angle Taper Pipe 2 is more than 1o, and the length of wide-angle Taper Pipe 2 determines according to design requirement and actual conditions, viscous to ensure
Clinker on the body of a gun is under heat shrinkage and the Action of Gravity Field of itself, clinker self falling.It is provided with the rear portion of oxygen rifle outer tube 5
Guide plate 6, the sealing shroud 7 of gun body are tightly connected by " O " type sealing ring 8 and lift cart.Led using gun breech by guide plate 6
To socket joint, realize and the quick grafting and centering of lift cart, the sealing shroud 7 of gun body pass through the fast sealing of " O " type sealing ring 8
Structure, it is quick fast to ensure that oxygen rifle is changed.
The utility model steel-making use steep-taper quick change oxygen rifle, have oxygen blowing it is steady, it is cost-effective, rational in infrastructure, province
The characteristics of Shi Shengli, the length of wide-angle Taper Pipe 2 requires according to producer and actual conditions determine, the taper of wide-angle Taper Pipe 2 is more than 1
O, oxygen rifle dry slag fast-falling can be made, solve the problems, such as steel making oxygen lance body of a gun dry slag.Realized by the guide plate 6 of gun breech and
The quick grafting and centering of lift cart, the sealing shroud 7 of gun body are sealed by " O " type sealing ring 8 and lift cart, ensure oxygen rifle
Enter, backwater and oxygen do not leak.The service life of oxygen rifle, the overall technology performance of oxygen rifle are greatly enhanced.
